Steps to reproduce:
0) Find a wiki with nasty captchas and abusefilters, for instance es.wiki (cf. https://es.wikipedia.org/?diff=prev&oldid=77941312 )

1. Attempt an edit which triggers both an abusefilter and the captcha (e.g. https://es.wikipedia.org/?diff=prev&oldid=77983188 due to T75067, see https://es.wikipedia.org/w/index.php?title=Especial:RegistroAbusos&dir=prev&offset=20141104104513&limit=1&wpSearchUser=Federico+Leva+%28BEIC%29 )
2. Enter the captcha upon reload, save
3. See the AbuseFilter warning, save
4. Enter the captcha again, save

I. Observed: Finally, success!
II. Expected: steps 3 and 4 should not be needed: the warning should be displayed in step 2 and at any rate there shouldn't be a step 4.

Note, eliminating reload in step 2 is T21648.
